The solvation dynamics of two organic molecules, namely rhodamine and cryptocianine in normal and deuterated water, was studied using ultrafast four-photon spectroscopy with pulses longer than the electronic transition dephasing. The isotope effect on solvation dynamics of solutes in H2O and D2O was measured. The shapes of solvation correlation functions were obtained by fitting the experimental data with the theoretical model calculations. It has been demonstrated that, depending on the excitation frequency, different methods of transient four-photon spectroscopy can provide information concerning the solvation dynamics either in the ground or in the excited electronic states of the solute.
